Our galaxy could harbour a billion planets similar to Earth
nets have already been detected in orbit around stars, but they contain mainly gas, and thus closer to Jupiter than Earth.
LONDON, (AFP) - One billion planets like Earth, capable of hosting life could exist in our galaxy, according to new research made public Wednesday by astronomers British Open University.
Researchers have developed a new model of computer simulation that allows you to estimate how many solar systems are likely to harbour planets similar to Earth, including their moisture and temperature.
Their conclusion, presented Wednesday at the National Congress of astronomers in Bristol, is that there could be at least a billion planets like Earth capable of harbouring life. Astronomers believe that this is a matter of time before telescopes capable of spotting them are developed.
There could be at least one billion others' land 'in the Milky Way, and more if we find solar systems more similar to ours, with giant planets remote areas habitable, "declared Professor Barrie Jones .
The calculation system plans' Lands' hypothetical orbiting in areas with moderate temperatures may allow human life, modelled on the 'Goldilocks zone' (Loops gold), which runs in our solar system l 'orbit of Venus to that of March.
The calculation system then establishes the extent to which these planets similar to Earth are likely to be ejected by the gravitational fields of nearby planets more important.
Nearly 100 planets have already been detected in orbit around stars, but they contain mainly gas, and thus closer to Jupiter than Earth.
The solar system known as so far the closest ours is' 47 Ursae Majoris', a star a little older than the sun. The solar system is located 51 light-years from Earth.
Two giant planets have been detected orbiting the star. However, the presence of these two planets and their gravitational fields do not exclude the existence of a planet earth type. The solar system is worth exploring because it is home to perhaps life, "said Professor Jones.
